Clean up stale Azure AD devices

Thu, 10 Jan 2019 22:25:00 +0000

If you are using Azure AD and the time passes you’ll have a lot of old device entries. If you enable the automatic device cleanup rule in Microsoft Intune the device is only removed within MDM and the Azure AD entry still exists.

Intune device cleanup rule

For this reason I created a tiny PowerShell snippet to create a report with all devices which didn’t contact your Azure AD tenant since the treshold date specified. If you confirm the operation you can also delete all affected devices.

Please be careful when running the script because when removing a device from Azure AD the stored Bitlocker recovery keys are also removed. I can recommend Roger Zander’s Azure table-based Bitlocker recovery key solution.

Set Office 365 UsageLocation property with Azure automation

If you want to assign Microsoft licenses to your Azure AD users e.g. Microsoft 365 E3 licenses you can do this with group based licensing as described here. ~~The problem is that even with group based licensing the UsageLocation property for each user must be set individually.~~

Update: 13.01.2019: Since group based licensing is GA the tenant location is used if no UsageLocation is set on a user object. Use this guide if you want to manually assign licenses or override the tenant settings if you need to configure different UsageLocations.

Possible bulk and automation solutions

You can achieve this with the following options:

“Manual” trough Azure or Office 365 portal
PowerShell (must be triggered manually or through scheduled task)
Azure AD Connect synchronisation (UsageLocation populated in on prem AD)
Azure automation with PowerShell runbook as in this post 🙂

Azure automation sounds expensive?

Fortunately Azure automation offers 500 minutes of script runtime for free. Find more details under Automation pricing. Just to give you an idea: If the executed script has an average runtime of 1 minute you could run it (500 minutes / (30 calendear days / 1 minute script runtime)) = 16x per day. Each month. For free.
